Roger Clemens may have inadvertently gotten some security guards at the federal courthouse in Washington, DC into trouble after it was revealed they accepted signed baseballs from the former pitcher Roger Clemens after his criminal trial. Guards are prohibited from receiving gifts of any kind from criminal defendants.

Clemens was on trial last month on charges of lying about using performance-enhancing drugs. The case was ended in a mistrial after prosecutors showed inadmissible evidence. A new trial has not yet been scheduled.

Inter-Con Security Systems Inc., the company that employs the guards, is handling the investigation. Early reports indicate that one guard received as many as six baseballs signed by Clemens, and then gave them out to his colleagues at the courthouse. There’s no word yet on what type of punishment the security guards may face for the offense.
